Catalyst steel module structure

The invention relates to a catalyst steel module structure which comprises a catalyst unit and a steel module wrapping the catalyst unit. The steel module comprises two frameworks which are vertically arranged and symmetrically distributed front and back, two cover plates which are transversely arranged and symmetrically distributed up and down, and two side plates which are vertically arranged and symmetrically distributed left and right. Each framework comprises a rectangular frame and a plurality of beam strips which are transversely fixed between the inner walls of the left side and the right side of the rectangular frame and are sequentially arranged from top to bottom. The catalyst unit comprises a plurality of strip-shaped modules which are transversely arranged and stacked into a cuboid shape. According to the invention, the catalyst unit formed by stacking can be quickly put into reaction equipment at one time by virtue of the steel module, so that time and labor are saved; the reaction equipment can
